BOX,MAKING AND COVERING MACHINE.

Specification of Letters Patent.

Patented. Jan. 28, 1908.;

Application filed December 10, 1907- Serial No. 405.940-

To all whom it may concern:

Be it known that 1, WILLIAM RIGHTER Commas, a citizen of the United States of America, residing at \Vimbledon, Surrey, England, have invented a new and useful Improvement in Box Making and Covering Machines, of which the following is a specification.

In a prior s ecification "filed 9 July 06 of Serial 325424 have described certain means by which cardboard or like boxes may be made up and covered and the present invention relates to modified and more simple means whereby the same end may be accomplished.

As in the previous case I propose to employ a folding die secured to and supported upon the framework or bed of the machine when in use, but detachable, so that it may be replaced by others when required, the folding wings on the opposite sides of the die in this case being preferably operated by hand, while the opposite wings work at right angles thereto when a rectangular box is being made or covered may be in part operated by an operating lever or treadle and in part by hand.

The accompanying drawings illustrate a convenient form of construction of machine, in which Figure 1 is an elevation, partly in section, of the upper part of the machine, showing a box body in position for covering by a blank; Fig. 2 is a similar view, but including the lower part of the machine, and showing the box body partially covered. Fig. 3 is a plan view of the table and die mechanism of the machine and, Fig. 4 is a cross section on line :1; y of Fig. 2, looking in the direction of the arrow.

Referring to the drawings the folding die may, as shown, conveniently comprise a rigid base plate 1 having a projection2 (whereby it may be secured as by bolts or the like 3 to the adjustable framework which carries it) and folding wings 4, 4, and 5, 5, having secondary wing pieces 6, 6, and 7, 7, respectively hinged thereto.' The wing pieces 4, 4, preferably carry at their ends tucking in fingers 8, which latter may however be separately framework if desired, and the secondary wing pieces 6 and 7 may be provided with elastic pads 9 for turning in the covering material into the box body, the secondary wing pieces however not being required mounted on the when making up uncovered box bodies. The pads 9 may advantageously be formed of small rubber tubing either closed at the ends and provided or not with a small hole to permit of the escape of a portion of the contained air, or having open ends as shown. Similar pads may if desired be provided on other parts of the folding die such as at the bottom corners or other parts where pads are desirable.

The adjustable framework which supports the folding die may as shown conveniently comprise oppositely placed supports 10 capable of being set at any desired distance apart across the table or bed plate 11 of the machine and secured in the desired position by screws and nuts 12 or the like operating through slots 13 in the table'll. This arrangement permits of dies of various sizes being used and quickly and readily fixed in position.

Where as above stated the folding wings are to be in part operated by a treadle or lever a convenient construction is to have oppositely set closure levers 14 adjustably mounted on pivots 15 in supports 16 also adjustable by means of screws and nuts 18 or the like in slots 17 in the table 11 and at right angles to the side supports 10. For adjusting the position of the closure levers 14 in their supports 16, the latter are provided with openings 19 spaced apart for the reception of the pivots 15, conveniently in the form of screws.

The levers 14 themselves may as shown be provided with adjustable presser heads 20 movable in slots 21 in the levers 14 and secured in the desired position by adjusting screws 22 for operating upon various sizes of folding dies. The levers 14 are at their lower ends attached to chains or cords 23 which for convenience of operation may be passed over guide pulleys 24 mounted on the under side of the table or bed plate 11, and attached preferably through an additional cord or chain to a foot treadle 26, (Fig. 2).

For the plunger described in the former specification is substituted an arm 27 hinged or pivoted at 28 to supports 29 secured to the table or bed plate 11. The arm 27 carries a removable plate 30 secured by bolts or the like 31 to the arm and adapted to carry the box body as shown and said arm is jointed preferably with a ball joint 32 to admit of adjustment so that when the plate 30 is lowered it will register evenly with the rigid base 1 of the folding die, bolts or the like 33 being provided for securing the joint. The arm 2" is preferably normally raised (as shown in Fig. 1) and is held in its raised position by the action of the spring 34 and is lowered by a pulling member, such as the cord or chain 35 in which is interposed also a spring 36 which permits of a certain amount of con tinued motion to the pulling member after the plate 30 has come in contact with the die base 1, such additional motion being transmitted to the closure levers 14 operating upon the folding Wings 5, 5, by attachingthe chain or cord 35 to the foot treadle 26 as shown to which latter the chains 23 of the levers 14 arealso attached.

The levers 14 are-themselves normally held in their inoperative position (Fig.1) either by springs 37 as shown, or by their own weight.

The pulling member cord or chain 35 may ifdesired be operated by means of levers instead of the foot treadle shown, or the levers 14 andthe arm 27 may be lowered or oper- 'ated by hand if desire An adjustable stop 48 may be provided for limiting the upward movement of the arm 27, sai stop being carried in a slotted support 49 to which it is secured by a screw 50 additional openings 51 being provided in the stop 48 whereby its position relative to the arm 2-7 maybe varied.

Adjustable in the form of slotted bars 38 secured by clamping screws 40 to pivotally mounted supports 39 adapted to be moved into other positions such as 39 by means of screws 39 are provided so as to insure the covering blank 41 being properly placed to register with relation to the box body or frame 42 to be covered said guides being provided with pins 43, and with shaped-registering pieces 43 having rounded ends removably secured to the bars 38 by screws, and either or both of which may be-em loyed so that the blank 41 may be operate upon by the folding wings 4, 4, and 5, 5, without tearing.

Means may be provided for removing the finished boxes automatically on the return movement of the arm 27, such means conveniently comprising an arm 44, movably secured to an upright 45 pivotally secured to the base plate or table 11 of the machine by a tightening screw 46 (Fig. 3) and adapted to catch the edge of the box and remove it by concussion from the plate 30. The box may however if desired be removed by hand.

The device may conveniently be mounted upon a suitable stand or support 52 to the lower'part 53 of which the foot treadle 26 may be hinged at 54' (see Fig. 2).

The operation of the machine illustrated is as follows :-The box body 42 is placed on the plate'30 carried by the hinged'arm 27 and the covering blank41 placed in position on the folding die as shown in Fig. 1, the treadle 26 guides, conveniently as shownblank is held is then depressed so as to bring the box body 42 onto the covering blank 41 the side wings 4, 4, are folded in by hand and the corners turned in by the tucking fingers 8 carried by the side wings 4, 4 the end of the covering blank is also turned in, and the secondary wings 6 are turned in so as to press the covering blank 41 to the interior of the box body 42 the first set of folding wings 4 and 6 and the tucking fingers 8 are retired as the further motion of the treadle brings up the second or end sets of folding wings 5, 5, the secondary wings 7 of which are turned in by hand, after which the treadle 26 is'released and the'hinged arm 27 rises carrying the covered box, which is'removed from the holder by the-trip arm 44 or by fingers or other suitable mechanical or pneumatic'device. If a box or boxbody is to be made then the blank would be placed on the folding die, the hinged arm 2-7 would be lowered to hold same, the rest of the operation being the same as for covering a box except that the secondary wings 6, 7, would not be required.

It will be evident from the foregoing that the invention though simple and specially suitable for operating by hand, treadle, or both combined, can also, if a greater effect is required, be worked by power, and-all of the arm under the influence of said spring,

resilient pulling devices for swinging the box holding means into contact with said die, and means for folding the box blank subsequently to and independently of the movement of said box holding means to clamp the blank, substantially as described.

2. In a box making and covering machine and in combination a hinged arm, a rigid die having foldin wings upon which a box y said arm to be folded, an adjustable framework for rigidly su porting said die, means 'for adjustlng sai framework, adjustably mounted ivotal levers for folding the die wings and b ank on two sides thereof, adjustable supports for said levers, means for adjusting sa1d su ports and means for operating said levers subsequently to the operation of and independently of said arm.
